4.4.1 General
The BlueCool S-Series is an air-conditioning system with its four
basic components, i.e. compressor, condenser, evaporator and
throttle element.
■
Evaporator (air heat exchanger)
Refrigerant vaporises at low pressure and a temperature below
the ambient temperature of the evaporator. It absorbs heat from
the ambient air in the process.
■
Compressor (refrigerant compressor)
The refrigerant vapour extracted from the evaporator at low pres-
sure is compressed to a higher pressure, and therefore to a higher
temperature. In the process, additional heat is fed to the refriger-
ant.
■
Condenser (sea water heat exchanger)
The compressed, heated refrigerant vapour is condensed at a tem-
perature which is above the sea water temperature. In the pro-
cess, the entire heat absorbed in the evaporator and compressor
is given off to the sea water.
■
Throttle element (capillary tube)
The pressure in the refrigerant subjected to condensing pressure is
relieved and transferred to the evaporator.
4.4.2 Cooling operation mode
The air-conditioning system absorbs heat form the cabin air in the
evaporator and cools it down by approx. 15°K. The cooled air is
blown into the cabin with the fan. The compressor now com-
presses the refrigerant vapour, which is then condensed to a liquid
when flowing through a condenser cooled with sea water. The
heat released is emitted to the sea water. The condensed refriger-
ant passes through the throttle element and the pressure is re-
lieved to form wet vapour on entering the evaporator. The liquid
component of the refrigerant is now evaporated and again takes
up heat from the cabin air. As a result, the refrigerant circuit is
closed.
Notes
With these air-conditioning systems, sea water flows
through the condenser, which is sucked in via a
pump. This ensures the cooling process.
BlueCool S-Series air-conditioning systems are de-
signed for maximum sea water temperatures of 35
°C.
